Background
It has been observed that some bugs (particularly performance-related ones) can take weeks to resolve, and often cannot be reproduced by the CPS dev team.
This proposal is to improve ways of working around bugs to reduce time spent.
Bug Reporting Template
Many bug tickets lack basic information such as what version was tested.
It is proposed that in addition to CPS FSA Template, a Bug Reporting Template be created. At a minimum, the following information should be provided:
- Full description of the issue
- Affected version(s)
- Expected behaviour (what is the requirement?)
- Actual behaviour
- Impact - this is important for setting priority
- Steps to reproduce - ideally a Minimal reproducible example
- (Optional) Attached artifacts: Screenshots, Logs, Test data, etc.
- Environment
- Attached the corresponding IDUN Jira
There has been much confusion about the number of CM-handles the bug reporters are testing with. In many tickets, phrases such as "80k deployment" is used, but in some cases this was 6k CM-handles, and 20k for others!
- Bug report should include how many CM-handles are registered
Performance Bugs
Performance issues are significantly more difficult to reproduce, being very sensitive the user's deployment/environment.
- Environment, including available resources in the deployment (memory and CPU cores, number of application instances)
- What is the load on the system (how many concurrent operations, etc.)?
- Measured CPU and memory consumption
- For Out Of Memory Errors (OOMEs): Attached heap dump - I think this should be a requirement moving forward
Client-reported bugs
Links to internal Jira tickets, Jenkins pipelines, should be provided where applicable. Logs etc. could be shared securely there.
Acceptance Criteria for Bugs
We need to agree on reasonable criteria, e.g.
- That CPS team has enough information to reproduce the bug
Sharing artifacts such as Logs in the Open Source
Some bugs being reported often require sharing information such as logs, heap dumps, etc. This needs to be done in a way that IPR is protected, since CPS is developed in the open source.
